Their earliest want must have been that of supplying below the earth the light they had lost above it; and at no time, even in the traditional period, do the races, of which the one I now sojourned with formed a tribe, seem to have been unacquainted with the art of extracting light from gases, or manganese, or petroleum.

They had been accustomed in their former state to contend with the rude forces of nature; and indeed the lengthened battle they had fought with their conqueror Ocean, which had taken centuries in its spread, had quickened their skill in curbing waters into dikes and channels.

To this skill they owed their preservation in their new abode.

"For many generations," said my host, with a sort of contempt and horror, "these primitive forefathers are said to have degraded their rank and shortened their lives by eating the flesh of animals, many varieties of which had, like themselves, escaped the Deluge, and sought shelter in the hollows of the earth; other animals, supposed to be unknown to the upper world, those hollows themselves produced." When what we should term the historical age emerged from the twilight of tradition, the Ana were already established in different communities, and had attained to a degree of civilisation very analogous to that which the more advanced nations above the earth now enjoy.

They were familiar with most of our mechanical inventions, including the application of steam as well as gas.
